Teacher Aldo stands in the lab.

Teacher Aldo is in his thirties, with short curly black hair and a goatee. He wears glasses and a blue Homework Zone T-shirt.

He says HEY THERE, IT'S
TEACHER ALDO HERE
AND WELCOME TO THE
HOMEWORK ZONE.
TODAY WE'RE
GOING TO DO A REALLY
NEAT EXPERIMENT,
GROWING PLANTS.
NOW YOU'RE
GOING TO NEED
A FEW ITEMS
AT HOME,
AND ONE OF
THE ITEMS IS SOME
PAPER TOWEL,
YOU'RE ALSO GOING
TO NEED AN
EMPTY GLASS
AND SOME BEANS THAT
YOU CAN FIND AT YOUR
LOCAL GROCERY STORE.
NOW WHAT
YOU WANT TO DO IS
YOU WANT TO GET AT
LEAST TWO OR THREE
SHEETS OF
PAPER TOWEL.
YOU WANT TO FOLD
IT A COUPLE
OF TIMES AND
WRAP IT UP NICE
AND TIGHTLY, AND
PLACE IT
GENTLY INSIDE
THE EMPTY GLASS.
JUST LIKE
THAT.
AND AT THIS
POINT IN TIME,
WHAT YOU WANT TO
DO IS YOU WANT
TO ADD A LITTLE
BIT OF TAP WATER.
JUST ENOUGH SO
THAT THE
ENTIRE PAPER
TOWEL GETS MOIST.
MAKE SURE YOU
GO AROUND
THE PAPER TOWEL AS
YOU POUR THE WATER,
AND THAT SHOULD
BE GOOD.
NOW WHAT
YOU WANT TO DO IS
YOU WANT TO EMPTY OUT
ANY EXCESS WATER,
JUST
LIKE THAT,
AND BRING THE
GLASS WITH
THE PAPER
TOWEL, AND NOW,
CHOOSE A BEAN,
AND YOU WANT
TO PUT IT
ON THE OUTSIDE,
IN BETWEEN THE
GLASS AND
THE MOIST
PAPER TOWEL.
NOW FOR THIS
EXPERIMENT,
YOU WANT TO
USE MORE THAN
JUST ONE
BEAN.
SO TRY TO USE
TWO OR THREE BEANS,
SO HOPEFULLY ONE
OF THEM WILL
BEGIN
TO GROW.
JUST LIKE
THAT.
AND NOW YOU'RE
READY!
SO WHAT WE'RE
GOING TO DO NOW
IS WE'RE GOING TO
TAKE THIS BEAN,
GLASS AND
PAPER TOWEL,
AND WE'RE GOING TO
PUT IT INTO LIGHT.
SO FIND A NICE
WINDOW SILL
NEAR YOUR
APARTMENT OR IN
YOUR HOME AT
SOME PLACE,
AND YOU'RE GOING TO
PUT THIS ON THE SILL,
AND THEN WHAT YOU'RE
GOING TO DO IS
YOU'RE GOING TO
WATCH AND OBSERVE.
GOOD SCIENTISTS
REALLY MAKE
OBSERVATIONS,
REALLY GOOD
OBSERVATIONS,
AND YOU'RE GOING
TO WATCH
HOW SUNLIGHT
INTERACTS WITH THE
WATER IN THE
TOWEL,
AND HOPEFULLY
YOU'LL HAVE A NICE
WARM AREA WHERE
THIS BEAN
WILL START
TO GERMINATE -
THAT MEANS
GROW.
NOW I'VE DONE THIS
EXPERIMENT AT HOME
AND I HAVE A COUPLE
OF STAGES
THAT I WANT
TO SHOW YOU.
THIS IS THE
BEGINNING STAGE,
MUCH IN THE SAME
WAY THAT I
JUST
SHOWED YOU HERE,
WHERE WE HAVE OUR
BEANS INSIDE
THE GLASS,
WITH THE MOIST
PAPER TOWEL,
AND THEN ABOUT
TWO DAYS LATER,
WHAT HAPPENS IS
YOU START TO
SEE THIS.
IF YOU
NOTICE,
THE SEED OF THE
BEAN OPENS UP
AND TWO
THINGS COME OUT.
ONE THING
IS
POINTING DOWN
AND ONE THING IS
POINTING UP.
THE PART
THAT'S POINTING DOWN,
THAT'S THE ROOT
OF THE BEAN,
AND THAT FACES
DOWN TOWARDS THE
CENTRE OF THE
EARTH.
THE OTHER
PART FACING UP
IS CALLED THE
BEAN SHOOT,
AND THAT WILL
EVENTUALLY HAVE
LEAVES ON IT AND
IT'LL FACE UP
IN THE SKY,
TOWARDS THE SUN.
SO WHAT HAPPENS IS
OVER A PERIOD
OF ABOUT TEN
DAYS, WHAT YOU'RE
EVENTUALLY GOING
TO GET IS
SOMETHING THAT
LOOKS LIKE THIS.
YOU'RE GOING TO
GET SOME
WONDERFUL
LEAVES SPROUTING
FROM THE INSIDE
OF THE BEAN,
AND SOME REALLY
STRONG ROOTS AT
THE BOTTOM,
LOOKING FOR WATER
TO DRINK.
SO THE
COMBINATION OF WATER,
SUNLIGHT AND HEAT
ACTUALLY MAKE
A
PLANT GROW.
TRY THIS EXPERIMENT
AT HOME
WITH
YOUR PARENT,
AND SEE PLANTS GROW
INSIDE YOUR HOME.
I'M TEACHER ALDO,
AND NOW YOU KNOW.
